I have successfully installed OpenBSD on my Asus EeePC 1001p, however I have a problem with it.

It seems the intel driver is not working with Intel GMA 3150.

So, I tried the vesa driver, it works, more or less....
My netbook's native screen resolution is 1024x600, but the vesa driver can only display 800x600, which really limits the already small netbook screen.
No matter what I tried to do in the xorg.conf file it just cant display 1024x600.

I heard that nonsense many times before. You need to increase refreshing rates. I have used VESA with the resolution 1600x1280 on the brand new DeLL laptop which comes with unsupported NVidia video card.

It is absolutely not true that VESA is limited to 800x600. Now if you are complaining about 3D acceleration and other goodies which usually come with real drivers that is another story and I agree 100% that VESA should be the tool of the last resort.

It seems you have misunderstood me due to my poor communication skills.

I tried to state that VESA is unable to display 1024x600 (let's face it it's a weird resolution, but that's the native resolution of my netbook) no matter what I do. I'm very well aware of the fact that VESA can be used for higher resolution than 800x600, but I have no idea if I can set 1024x600 and how.

Create xorg.conf file and then try increasing refreshing rates to about 40-110 and 50-120 as in this example
